Gupima Imashini Ipima Imbere (Gukwirakwiza Ibice by'Indabyo)

Gupima icyuma gipima ikwirakwira ry'umurima wa rukuruzi ku buso bwa rukuruzi - by'ingenzi cyane ku mpeta zifite ibiti byinshi.

Ihame:Imashini ya Hall izenguruka kandi igashakisha ku buso bwa rukuruzi, ikandika imbaraga z'aho iherereye kuri buri ruhande.

Intego:Genzura uburinganire hagati y'inkingi, imiterere y'umuraba w'umurima (ubuziranenge bwa sinusoidal/square-wave), n'ubudasa bw'umuraba w'inkingi mu mpande nyinshi.

Igipimo cy'ingenzi:Itandukaniro ry'umurima hagati y'inkingi zegeranye ntirigomba kurenga ± 3%; impeta zo gusimbuza zisaba ± 1%.

Abakiriya ba encoder bakunze gusaba raporo zo gupima imikorere ya Hall probe. Muri Fullzen, iki ni ikintu gisanzwe cya QC ku mpeta za encoder.

Uburyo bwo gukoresha ifu y'icyuma (Isuzuma ryihuse)

Uburyo bw'ifu y'icyuma ni bwo buryo bwo kugenzura neza cyane - ifu y'icyuma iterwa ku buso bwa rukuruzi ihuzwa n'imirongo y'amazi, igaragaza neza uko ubutaka bukwirakwira.

Intego:Kugenzura byihuse ko icyerekezo cya magnetization ari cyo, umubare w'imirongo ari wo, kandi nta nenge zigaragara za magnetization zihari.

Imbibi:Ifite ireme gusa; nta gaciro k'imibare gatanga. Ubunyangamugayo buri munsi cyane y'ubwa Hall probe scanning.

Uburyo bw'ifu y'icyuma bukoreshwa mu gusuzuma ibintu bya mbere no gutondekanya byihuse ku murongo w'umusaruro - ntabwo bukwiriye QC isohoka, ariko ni bwiza cyane mu gusuzuma ibintu bije no kwemeza vuba nyuma yo gukoresha magnetization.

Ibibazo Bikunze Kubazwa

Q: Ese magneti y'impeta ishobora kongera gukoreshwa mu cyerekezo gitandukanye nyuma yo gutangira gukoresha magneti?

A: Oya. Ku bijyanye na magneti za NdFeB zikozwe mu buryo bwa sintered, icyerekezo cya magneti kigenwa mu gihe cyo gukanda. Iyo magneti imaze gukoreshwa, kongera gukoresha magneti mu cyerekezo gitandukanye ntabwo bizakora kuko domaine za magneti ziba zamaze kujyana. Niba ukeneye guhindura icyerekezo cya magneti, ugomba gutumiza magneti nshya zifite icyerekezo gikwiye mbere yo gukanda. Muri Fullzen Technology, twemeza icyerekezo cya magneti mu cyerekezo cyo gusuzuma igishushanyo kugira ngo wirinde iki kibazo.
